It looks like Kit Harington is officially dating ex-girlfriend Rose Leslie again. After the redhead's character Ygritte was killed off the HBO hit series it seems Jon Snow can't let her go on or off screen.

According to Us Weekly, a source revealed, "They've been back on for about three months," adding, "That said, it's casual right now and they're having fun. They're not moving in together or anything like that yet."

The "Game of Thrones" season 4 cast members, Harington and Leslie, both 27, split after dating for one year last August. The hot actors first sparked rumors of a reconciliation last month when they were photographed arriving at Los Angeles International Airport together before attending a panel for the George R.R. Martin based series at Comic-Con in San Diego.

The British stars knew each other prior to filming the HBO show together and their friendship eventually turned romantic while working on set. Back in March, Rose Leslie only had nice things to say about her on-again boyfriend.

When speaking of Kit Harington the actress said, "I don't think he considers himself a heartthrob," adding, "He's a lovely man!"

When spotted at LAX together, the red hair beauty kept her look super casual wearing sweat pants and a semi-sheer white tank top. Meanwhile, her off again, on again boyfriend Kit Harington who played her on screen love Jon Snow wore a pair of jeans and a blue T-shirt.

The hot actor was previous romantically linked to his costar Emilia Clarke. Harington admitted that he was all about dating the brunette beauty at least for the sake of the show and onscreen.

The relationship between the two cast members' characters, Jon Snow and Darnerys Targaryen is set to blossom in the upcoming seasons.
